h) Diode test
Make sure that all circuit parts, circuits and components and other objects of measurement are
disconnected from the voltage and discharged.
- Turn the DMM on and select measuring function
- Pressthe“SELECT”button2xtoswitchmeasurementfunc-
tions. The display shows the diode symbol and the unit Volt
(V). Pressing this button again takes you to the next measur-
ing function, etc.
- PlugtheredmeasuringlineintotheΩmeasuringjack(E)and
the black measuring line into the COM measuring jack (D).
- Check the measuring lines for continuity by connecting the
two measuring prods. The value must be approximately
0,000 V.
- Connect the two measuring prods with the object to be
measured (diode).
- Thedisplayshowsthecontinuityvoltage“UF”involt(V).If
“OL” appears, the diode is measured in reverse direction
(UR) or the diode is faulty (interruption). Perform a counter-
pole measurement to check.
- Remove the measuring lines from the object to be meas-
ured after completion of the measurement and switch off the
DMM.
i) Continuity test
Make sure that all circuit parts, circuits and components and other objects of measurement are
disconnected from the voltage and discharged.
- Turn the DMM on and select measuring function
- Press the “SELECT” button 1 x to switch measurement
functions. The display shows the symbol for continuity
testingandthesymbolfortheunit“Ω”.Pressingthisbutton
again takes you to the next measuring function, etc.
- PlugtheredmeasuringlineintotheΩmeasuringjack(E)
and the black measuring line into the COM measuring jack
(D).
- Acontinuityvalueof≤10Ωisidentiedascontinuity;in
this case a beep sounds. The measuring range is up to
600Ω.
- If “OL” (overload) appears on thedisplay,youhaveex-
ceeded the measuring range or the measuring circuit is
interrupted.
- Remove the measuring lines from the object to be meas-
ured after completion of the measurement and switch off
the DMM.
